LD_PRELOAD=lib using ldopen: can't resolve symbol '_dl_open'

[joost@rulcmc.leidenuniv.nl (joost witteveen)]

I'm trying to LD_PRELOAD a library that in turn uses ldopen.
this works OK, as long as I don't try to run (with LD_PRELOAD
set) any binaries that use libdl themselves.

Should this be possible? If so, what am I doing wrong?


$ cat libfoo.c 
#include <dlfcn.h>
void foo(){
  void *handle=handle = dlopen("/lib/libc.so.6", RTLD_LAZY);
  dlclose(handle);
}

$ gcc -shared -Wl,-soname,libfoo.so.0 -o libfoo.so.0.0 -fPIC libfoo.c -ldl

$ export LD_PRELOAD=./libfoo.so.0.0 
$ bash  
bash: can't resolve symbol '_dl_open'
bash: can't resolve symbol '_dl_close'
bash: can't resolve symbol '_dl_catch_error'
$ ls -d .
./


Thanks.
